To do this, the generated signals are transmitted to the subscribers participating in the communication session for promptly changing the parameters of the software movement, in order to prevent the "break" of communication. On the mobile object, an onboard module for estimating the line-of-sight range and signal-to-noise ratio is introduced, and in the ground complex, a ground-based unit for estimating the line-of-sight range and signal-to-noise ratio, a calculator of parameters for organizing communications, and a unit for displaying information on organizing communications are introduced.
